Class notation for Dynamic Positioning System.

Purpose

The dynamic position system is regarded as the complete installation necessary for dynamically positioning vessels, and includes a power system, thrusters, DP-control system.

Benefits

The notation ensures that the vessel has a system which is sufficient to meet class requirements for an automatic Dynamic Positioning System without any redundancy.

Features

The following documentation is applicable:

• Instrumentation and automation; dynamic positioning control and monitoring system, thrusters, mode control selection, position reference systems and sensors

• DP control centre arrangement and layout documentation

• Programs for tests and trials

• Electric power system documentation; such as electrical load calculation during dynamic positioning operation

• Calculation of the environmental regularity number evaluation, ie, the ability to keep in position relative to weather conditions

The scope of the DP notation covers certification of the DP systems, verification/review of the related machinery systems and comprehensive testing of the DP functionality.
